IMO scraping is only abusive if the site explicitly asks to not be scraped (via the site's robots.txt)
There are plenty of ways to scrape responsibly.
Scraping, when done responsibly (respecting robots.txt and not overloading a server with requests) wouldn't be considered abusive in most cases. While we will be strict in enforcing abuse policies, when it's obvious a user acted with good intentions we can work on a case by case basis.
